I am trying to display a PDF file that I have on disk using this: <div> <h4>PDF File:</h4> <%= @data %> </div> However, the page looks like gibberish. Same if I use <%= Phoenix.HTML.raw @data %>

To render it in the middle of the page you’ll need to leverage some javascript https://stackoverflow.com/questions/291813/recommended-way-to-embed-pdf-in-html

in your controller set the appropriate content type and then stream the payload into the conn.

Thanks! I just added the put_resp_content_type line. Now I don’t see gibberish, but rather PDF viewer. However, there is an error message:“This PDF document may not display properly”. I do know that the PDF file is OK. Do I need to do something else to stream? {:ok, body} -> conn …

No, more like this: {:ok, body} -> Enum.into(body, put_resp_content_type(conn, "application/pdf")) But thats in theory… I never actually used the fact that Plug.Conn is a Collectable.

[image] NobbZ: |> Enum.into() Thanks, I’ll look into that. I think more arguments are required by Enum.into( )

@jxxcarlson are you trying to send them a pdf file? or render it inline with html? If you’re just sending them a file then use Plug.Conn — Plug v1.20.2
